RAILWAY-CAR DRAFT-RIGGILIG.

To all whom it may concern:

' Be it known that I, Gnome A. JoIINsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Railway-Car Draft-Rigging, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Thisinvention relates to improvements in railway car draft riggings. and more particularly to the yokeemployed therewith.

An object of the invention is to provide a draft rigging for railway cars employing a two piece yoke and having cooperative means on t io yoke and a follower for preventing lateral separation of the yoke parts.

Another object of the invention is to provide a two piece yoke of novel and cheap construction and which is efficient in operation.

In the drawing forming a part of this specification, Figure 1 is a' side elevation of a portion of a draft rigging showing my improvements in connection therewith. Fig. 2 is a horizontal sectional view'taken substantially on the line 22 of Fig. 1, the yoke being'shownin plan. Fig. 3 is a verticalsectional view taken substantially on the line 33 of Fig. 1 and Fig. 4 is a perspective View, upon an enlarged scale, showing the butt end of the coupler, a half of the yoke and the front follower associated therewith.

In said drawing 10-.10 denote the center sills or the draft members having the stop plates 11-11 secured to the inner sides thereof, each stop plate being provided with front stop shoulders 12, rear stop shoulders 13, front intermediate stop shoulders 14 and rear intermediate stop shoulders 15. The

stop castings are furthermore provided with limiting stops 16 for all the followers. A designates the yoke which, as shown, comprises two like members 17--17. Each member 17 has upper and lower horizontally extending arms 18 and 19 connected at the rear as at 20 and provided with a rear filler 21 and a connecting thimble 22, the latter being substantially channel shape in horizontal cross section. At its forward end each member 17 has its upper and lower arms indented as indicated at 23, the free Specification of Letters Patent. Patented Apr, 24,1917.

tions 2727, these projections being so' spaced from the gibs 24-24 that the enlarged coupler butt is adapted to be received therein, the back end of the coupler butt engaging the members 2727. Eabli member 17 of the yoke is provided at its rear end with a hinge lug 28 and at its forward end On their inner with upwardly and downwardly extending cars 29, said hinge lugs 28 and ears 29 being perforated as lndicated at 30 to receive a bolt 31 therethrough, the bolt at the rear extending vertically and those at the front extending horizontally as clearly appears from Figs. 1 and2. Mountedwithin the yoke is a front follower 32, intermediate followers 33 and 3%,and rear follower- 35, the followers having interposed therebetween springs 36 which may be of any well known or desirable construction. As shown, the front fol-lower 32 is recessed on its upper and lower edges as indicated at 136 thus leaving upwardly and downwardly extending projections 37 at the four corners of the follower. The height ofjzhe central portion of the follower 38 corresponds to the distance between the opposite ends of the members 2727 so that the follower can he slipped in between said members of the yoke and the projections 37-37 will engage the outer sides of said members 27. As shown in Fig.

1, the opposed faces or edges 39-of the memtate the entrance of the portion 28 of the front follower thereinto upon relatively longitudinal ,niovement between the follower and yoke. The followers, andv hence the gear itself and yoke, are supported by straps 40 secured to the stop members by olts or other suitable deviees'in any well known manner. It will also be noted, by inspection'of Figs. 2 and 4, that the outer edges of the upper and lower arms of e ch draft yoke member is inclined as shown a 41.

' In assembling the devices," the followers 33, 34 and 35 and the springs 36 are inserted in the us al manner and the front follower 32 is firstinserted transversely through the which the spring between said follower 32 and the front intermediate follower 33 can be inserted. Under buff, the draw-bar. engagesboth the members 2T27 and the front follower and compresses the front spring 36 against the follower 33, the rear spring being compressed in the usual manner through the intermediary of the follower 34 and intermediate yoke thimble.- Under draft, the followers 33 and are moved forwardly compressing the springs against the followers 32 and 34, the latter remaining stationary. By employing a follower recessed or cut away as applicants front follower 32 and having the eorner extensions thereof engaging portions of the yoke parts, said follower prevents the lateral separation of the two part yoke and the use of the bolted ears 29-29 may be optional. It will also be aparent that the use of a cut or notched folower, such as applicants front follower 32, is not necessarily confined to the front follower.

Although I hare herein shown and described in detail one form of my invention. the same is merely illustrative and I eontemplate all changes and modifications as come within the scope of the claims appended hereto.

1. In a railway draft rigging, the combination with a yoke formed of two parts and divided centrally longitudinally, each of said parts being in the form of a loop and havingvinwardly extending, opposed BEST AVAILABLE COP projections, of a follower extending transversely through said yok said follower being cut away on its upper and lower edges. the narrow portion of said follower formed by said cut away mrtlronsj eng adapted to 40 be seated between said -||nvardly extended projections formed on the yoke parts.

2. In a railway draft rigging, the rombination with a yoke consisting of two parts. each part being in the form of a loop and hat-ing opposed, inwardly extending II'UjCC- tions near the forward end thereo 'of a front follower extending through said yoke. said follower being eut away on the top and bottom edges thereof and adapted to'be received between said inwardly extending projeetions on the yoke members.

3. In a draft rigging for railway ears, the combination with a two-part yoke. the parts being separable and having a division line extending longitudinally and centrally thereof. said yoke parts when assembled having a hood at the forward end thereof within which is adapted to be received a butt of a standard draw an r. said yoke being provided with downwardly and upwardly pro jet-ting flanges at the rear of said hood and against which the rear face of the draw bar butt is adapted to bear, of an H-shaped follower extending 'transiersely through the yoke and adapted to lit between said llanges.
